摘要
介绍了以高岭土为原料 ,经盐酸预处理后 ,加水聚合、调整反应液 pH ,制备液体聚合氯化铝净水剂的新工艺。对所得产品的净水性能和技术指标进行了测定 ,结果表明 ,采用该工艺制得的聚合氯化铝产品技术指标符合GB1 5892—
A new process for preparing liquid polyaluminium chloride coagulant is introduced.It uses kaolinite as raw material,which is pretreated at first with hydrochloric acid,and then mixed with water for polymerization and at last adjusted for pH.The product performance is determined and it can meet the standard GB15892-95.
